Abstract

See full text

A method of manufacturing carburized Lu2O3 doped Mo cathodes for thermionic emission for magnetrons is described. The Lu2O3 doped Mo powder is prepared by sol-gel method. The powder is reduced thoroughly in hydrogen atmosphere. Afterwards, the powder is die-pressed into pellets, followed by sintering in hydrogen and carburization in activated carbon powder to obtain the carburized Lu2O3 doped Mo cathode.
